Is LEED Online mind-numbingly slow today for anyone else? Or is it just me? I may give up and try again tomorrow. Frustrating as I was hoping to submit a final review today. :(

Hi All,

My team member is leaving Webcor, and unfortunately that means we have to fill her big shoes with someone new! I thought I'd reachout here and see if you know anyone of high caliber looking for a Sustainability Manager position?

Hi friends,

We recently tracked our water consumption on site during the structural demolition of some existing reinforced concrete buildings.  The new OSHA silica regulations required us to keep dust to virtually zero, so we had a bunch of mist cannons and water hoses pumping water around the clock.  We consumed ~855,000 gallons in a...

Under a high carbon scenario, most of North America will be 2 degrees C hotter by 2050. Meantime, we're designing buildings that will still be around in 2050, to codes that don't yet factor in chronic risks associated with climate change. I want to explain these risks to my colleagues; I'm hoping some of our green gurus can help answer the... Read more

We have a client who is asking us to design a roughly 10 ksf Wellness Center for PHIUS 2021 certification.  The program includes several high density assembly type spaces - roughly 300 person peak occupant load for the building.  The Criteria Calculator that the architect showed us puts the building peak cooling load at 4 BTUH/sf (3000 sf/ton...

Board insulation has good thermal performance ranging from about R-4 to R-8 and is used as an integral part of a building envelope’s continuous insulation system.

Because board insulation is used on the building exterior, it is not always subject to the same material health and emissions requirements as batt insulation used inside the... Read more

We have an increasing number of projects, where the client is coming to us with "net zero" aspirations and plans, some of which don't fit the typical all-electric, grid-tied building that produces 100%+ of its annual energy use on-site.  There include examples like:

1) A (targetd) living building that maximizes on-site production, with... Read more
